Richard Feynman on Entropy | Does the Past Still Exist?

Описание: Why does time only move forward?
Broken cups don’t reassemble.
Mixed ink never separates.
We remember the past, not the future.
As Richard Feynman explained, the laws of physics themselves do not forbid time from running backward. Every fundamental interaction works the same both ways.
The reason time feels irreversible is not force, but probability.
Order is rare. Disorder is common.
And the universe began in an unusually ordered state.
Since then, it has been quietly relaxing.
That imbalance is the arrow of time.

In this video, inspired by Feynman's legendary lecture "The Distinction of Past and Future," we explore the shocking answer. It's not in the laws—it's in PROBABILITY. The universe started ordered and has been falling apart ever since. That's entropy. That's time's arrow.
